Drinking clean water can be taken for granted. Explore the process and high cost of filtering water with a water pollution and filtration activity. Young scientist build a filtration system to filter polluted water, examine the economics...

In the 16th lesson in the series of 32 the class uses the concept of complex multiplication to build a transformation in order to reflect across a given line in the complex plane. The lesson breaks the process of reflecting across a line...

Scholars explore triangles with rods of different lengths. Using rods of 2, 4, 6, 8, and 10 cm class members build as many different types of triangles as they can. They also describe properties of these triangles and determine...

What does it take to build a stable arch? Pupils apply vectors and physics as they examine arched bridges and their structural integrity. They use vectors to represent the forces acting on the stone sections and make conclusions based on...

Building on prior knowledge of the pervious lesson in the series, pupils explain the previous lesson to each other. Then they write a simple guide for a young child to read on the same topic. 

Explore linear and nonlinear models to help your class build their function skills. In a continuation of the previous lesson, learners continue to analyze and sketch functions that model real-world situations. They progress from linear...

Make breaking a leg a less troublesome experience. Groups brainstorm designs for crutches that have devices that help carry items. They build prototypes of their devices to test out their designs.

Learners practice drawing Lewis dot structures, build molecules with model kits, and predict molecular shapes using VSEPR theory. The combination of written work and hands-on reinforcement benefits young scientists.

Gaps are essential to engineering bridges and roads. Learners watch a video showing a typical construction of a bridge to see why they're so important. They then manipulate an interactive to model the effects of temperature change on the...

Evidence shows the Vikings likely navigated by using a simple sundial to find their course. Videos, a short story, and discussion help bring this time period to life as they study European history with a hands-on experiment. Scholars...

It's electric! Young anatomists use Virtual Neurons software to build, control, and analyze complex nerve circuits within the body. Colorful and packed with content, class members enjoy interacting with the nervous system...

Take any number, multiply it by five, and then divide by five. Did you end up with the original number? In the same vein as the previous lesson plan, pupils discover the relationship between multiplication and division. They develop the...

Engineer an autonomous underwater vehicle (AUV) to study concepts of physics. Using household materials, collaborative groups design and build an AUV and then test Newton's Laws of Motion as they apply them in underwater environments...

Combine total quantities and equivalent ratios in problem solving. The fifth instructional activity in a series of 29 presents problems that can be solved using equivalent ratios. Pupils use part-to-part ratios and either sums or...

It seems the post office has run out of stamps! Learners build all the values of postage available if the post office only sells five- and seven-cent stamps. The task provides an opportunity to create an expression in two variables and...

Go with the flow! The eighth installment in a 13-part series has earth science students dive in to the world's system of ocean currents. The interactive illustrates the different types and depths of currents, how wind and gravity...

Inventor, astronomer, surveyor, mathematician, clock maker. Learners celebrate the life of Benjamin Banneker by building creative analog clocks, making scale models, and solving problems related to surveying. The activities model the...

Play a game of capture the points. Young scholars receive a number line with specific points graphed and must write an inequality that captures all the points. The second task of the algebra project is to write an inequality with...

A good concept map requires high thought processes. This makes it a great tool for teaching and evaluating your pupils. A helpful article describes a great approach for teaching young scholars the art of concept map building and how best...

Pregnant women exposed to PAH air pollution increase the risk of obesity in their children. The example of epigenetics, along with others, builds the basis for understanding the process of cell differentiation. Scholars view a video,...

How are forces and motion important to a swing set? Scholars explore the concepts of force and motion using swing sets. In preparation for their own STEM design project, individuals take surveys and data from peers, complete labs on...

Viewers learn about three different weather measurement tools in installment five of the 10-part Discover Your Changing World series. They build weather vanes to collect data on wind speed, barometers to determine air pressure, and...
